According to the scope of use of the fixture classification and related introduction
The classification of fixtures can be classified according to the scope of use. This article takes the opportunity to briefly introduce the knowledge, so that more people have knowledge of fixture classification and related presentations. The specific content can refer to the details of this article.
Fixtures can be divided into general fixtures, special fixtures, combination fixtures, universal adjustable fixtures, and group fixtures, depending on the scope of use. Machine fixtures can also be classified according to the machine they are used on and the power source that generates the tightening force. According to the machine tool used, fixtures can be divided into lathe fixtures, hydraulic fixture, drilling fixtures (drilling jigs), boring machine fixtures (grinding tools), grinding machine fixtures, and gear machine fixtures, etc. The fixtures can be divided according to the power source that generates the tightening force. Manual jigs, pneumatic jigs, hydraulic jigs, electric jigs, electromagnetic jigs, vacuum jigs, etc. Fixture design is an important part of the mechanical processing system.
In order to ensure the processing requirements of a workpiece in a certain process, the workpiece must be in an accurate relative position with respect to the cutting or forming motion of the tool on the machine tool. When fixtures are used to process a batch of workpieces, this requirement is achieved through fixtures.
The parts are relative to the fixture, the fixture is relative to the machine tool, and the part is relative to the machine tool. The final accuracy of the workpiece is obtained by the part relative to the machine tool. So "positioning" also involves three layers of relationship: the positioning of the workpiece on the fixture, the positioning of the fixture relative to the machine tool, and the positioning of the workpiece relative to the machine tool is indirectly ensured by the fixture.
